قَالَ مَالِك : لَيْسَ فِي عِشْرِينَ دِينَارًا نَاقِصَةً بَيِّنَةَ النُّقْصَانِ زَكَاةٌ ، فَإِنْ زَادَتْ حَتَّى تَبْلُغَ بِزِيَادَتِهَا عِشْرِينَ دِينَارًا وَازِنَةً فَفِيهَا الزَّكَاةُ ، وَلَيْسَ فِيمَا دُونَ عِشْرِينَ دِينَارًا عَيْنًا الزَّكَاةُ
Imam Malik, may Allah have mercy on him, said: If twenty dinars are so light in weight that their value does not reach the full twenty dinars, then there is no zakat on them. If they are more than twenty and their value is equal to the full twenty dinars, then zakat is obligatory on them. And there is no zakat on less than twenty dinars.
